Binary Grid
Fill every square of the 8×8 grid with a 0 or a 1.
The rules
- No more than two of the same digit next to each other in a row or column. So 0 0 0 and 1 1 1 are not allowed.
- Every row and every column has four 0s and four 1s.
- No two rows are exactly the same, and no two columns are exactly the same.
- There is only one correct answer.
How to play
- Tap an empty square once for 0, twice for 1, and a third time to clear it. Solid squares are given and can’t change.
- A red outline marks three in a row, or a line with too many of one digit.
- Fill the grid correctly to earn today’s green check.
Tip: two matching digits side by side must have the other digit on both ends, and a gap between two matching digits must be the other digit.
